Use this practical Indoor Comfort ComboKit to handle all relevant measurements in order to evaluate the indoor air quality in indoor areas and to determine the draught risk and degree of turbulence in workplaces. The multifunction measuring instrument, the CO2 probe and the turbulence probe all feature an intelligent calibration concept, ease of use and maximum convenience for carrying out comfort level measurements.

No task is too challenging, no application too specialized: the testo 440 combines a compact hand-held measuring instrument with intuitive measurement menus and a wide selection of air velocity and IAQ probes (please order separately)

Clearly structured measurement menus: thanks to the menu guidance programmed into the instrument, you can determine the degree of turbulence and draught risk easily and reliably, in accordance with EN ISO 7730 and ASHRAE 55. Other practical measurement menus, e.g. long-term measurement: for long-term monitoring, enter the measurement time and measuring cycle in the measuring instrument and record measurement data trends

Easy storage and evaluation of measurement data. Measurement data memory for up to 7500 measurement protocols, which can be read via a USB port and further processed as a CSV file on the computer (e.g. with Excel)

Practical magnets for easy attachment of the measuring instrument to metal surfaces
